遞歸查找文件夾中的所有 .php 文件

Question

使用 PHP，如何在文件夾或其子文件夾（任何深度）中找到所有 .php 文件？

Answer 1

您可以使用RecursiveDirectoryIterator和RecursiveIteratorIterator ：

$di = new RecursiveDirectoryIterator(__DIR__,RecursiveDirectoryIterator::SKIP_DOTS);
$it = new RecursiveIteratorIterator($di);

foreach($it as $file) {
    if (pathinfo($file, PATHINFO_EXTENSION) == "php") {
        echo $file, PHP_EOL;
    }
}

Answer 2

只需添加如下內容：

function listFolderFiles($dir){
    $ffs = scandir($dir);
    $i = 0;
    $list = array();
    foreach ( $ffs as $ff ){
        if ( $ff != '.' && $ff != '..' ){
            if ( strlen($ff)>=5 ) {
                if ( substr($ff, -4) == '.php' ) {
                    $list[] = $ff;
                    //echo dirname($ff) . $ff . "<br/>";
                    echo $dir.'/'.$ff.'<br/>';
                }    
            }       
            if( is_dir($dir.'/'.$ff) ) 
                    listFolderFiles($dir.'/'.$ff);
        }
    }
    return $list;
}

$files = array();
$files = listFolderFiles(dirname(__FILE__));

很晚了。 但我認為這對那些在搜索后登陸這里的人有用。

我修改了supajason創建的代碼因為提供的代碼沒有返回一致的結果：主要是由於使用的命名法。

我還添加了一些功能。

希望有用！

define('ROOT', str_replace('\\', '/', getcwd()).'/');

Answer 4

這類似於此處的另一個答案，但刪除了SKIP_DOTS ，並與strict_types一起strict_types ：

<?php

$o_dir = new RecursiveDirectoryIterator('.');
$o_iter = new RecursiveIteratorIterator($o_dir);

foreach ($o_iter as $o_info) {
   if ($o_info->getExtension() == 'php') {
      echo $o_info->getPathname(), "\n";
   }
}
